VINCENTpartial4

Blending anatomical accuracy, a modular design, sleek aesthetics, a lightweight carbon-titanium build, and customisable fit, the VINCENTpartial4 empowers users with superior performance, precise, natural movement and enhanced dexterity and grip.

Durability & Materials

  • Waterproof to IP68 - fully sealed against dust and water (including the wrist), enabling continuous submersion up to ~1.5 m for around 30 minutes without restrictions on water type.

  • Constructed on a high-strength aluminium frame, with an optional titanium frame for extra ruggedness.

  • Features elastic base joints and spring-loaded finger elements that adaptively adjust around objects, enhancing grip and adaptability.

  • Encased in silicone covers, offering improved hygiene, durability, tactile feel and a natural grip.

Wrist Integration & Bilateral Use

  • Four wrist variants available, from transcarpal to quick-snap with
    bendable joint.

  • Designed and optimised for bilateral amputees, ensuring consistent
    functionality on both sides.

Control & Grip Selection

  • Features an intuitive gesture-based control system (“single trigger control”) - no external
    switches needed, just cleverly structured open/close impulses.

  • Allows selection of up to 14 preset grip patterns, with capacity for users to define additional ones via an app—totaling up to 32 grips and positions.

  • Control signals, grip selection, locking, and battery status are visible and adjustable directly on the hand for ease of use and optimal functionality.

Sensory Feedback & Adaptive Grip

  • Offers vibrotactile feedback - small vibrations correspond to applied force, giving the user a refined “sense of touch”.

  • Adaptive grip is enhanced through both the tactile design and internal feedback mechanisms, aiding object handling.
